From a pad perspective there might be a difference; Phillips specified a

Mode is just a definition here;
0-100kHz SCL clock: normal
100kHz-400kHz SCL clock: fast
400kHz-(3.5MHz) SCL clock: high speed

For the core there's no difference, just program the divider to achieve the
desired frequency.

different pad type for the high speed devices. Although you might achieve
good results using normal pads.

Subject: [oc] i2c speed - for master core

Hi,
I looked in your i2c master core and according to the spec it is 
supporting all different speeds - normal,fast and high_speed.
One thing that I did not understand is how changing of speed is done in 
your implementation and how can the user program the master to work 
in each one of the speeds.
Can you elaborate on this?
This would help me a lot.
Thank you,
omer pessach
